Car Subwoofer Amplifier Driver

The stereo signals coming from the line outputs of the car radio amplifier are mixed at the input and, after the Level Control, the signal enters the buffer IC1A and can be phase reversed by means of SW1. This control can be useful to allow the subwoofer to be in phase with the loudspeakers of the existing car radio.
Then, a 12dB/octave variable frequency Low Pass filter built around IC1B, Q1 and related components follows, allowing to adjust precisely the low pass frequency from 70 to 150Hz.
Q2, R17 and C9 form a simple dc voltage stabilizer for the input and filter circuitry, useful to avoid positive rail interaction from the power amplifier to low level sections.

Sub-Woofer Amplifier 100 Watt

This is the circuit of subwoofer amplifier. This amplifier can produce an output of 100Watt. There are seven transistors including four in the output stage. The transistors Q1 and Q2 form the preamplifier stage. Transistors Q4 to Q7 form the output stage. Since no ICs are used the circuit is very robust and can be easily assembled on a general purpose PCB.

Rangkaian Subwoofer 200 watt

Skema rangkaian Subwoofer

If we walk in the shop or mall and see the electronic equipment is high end, so sometimes we desire to have the equipment, for example, we see that a subwoofer bass sound is so excite. but for the price of our audio equipment may still include expensive

As an electrician we have any idea, how to make a quality subwoofer, such as not lose it in the store, but with an affordable cost.

Music of heave fluty, plus the subwoofer with the boom of the formations, it is that we want to show in this project. a series of simple and inexpensive numun able to meet the conditions above.

Active Subwoofer (rangkaian subwoofer) is a series of Simple and simple before trying this series to prepare yourself to listen to the crack formations that will be generated by this series. power amplifier for its series, please use the power that you like our previous post. However, to use the results of the maximal power with a higher power. for example, using the power that has STK4050 power 200 watt.
